The store is only offering it to over-25s. You have to book and can only arrive at your appointment after a telephone consultation with a nurse. I take a deep breath and book. I’m nervous but excited.

Tim Goodacre, of the Royal College of Surgeons, and David Ward, president of the British Association of Plastic, Reconstructive and Aesthetic Surgeons, have written to Superdrug with concerns that these treatments could become “impulse buys” among shoppers.

But I have to go through a phone conversation with a nurse first, who explains the difference between Botox and fillers. She asks a little about my medical history and tells me the cost. It’s £99 for crow’s feet and another £99 if I want the wrinkly furrowed brow between my eyebrows sorted, too.

Within 48 hours, I’m in Superdrug at The Strand. My “aesthetic nurse prescriber” leads me into the treatment room for a 45-minute consultation. She goes through my medical history and asks what I want to achieve.

Superdrug says all its nurses are highly trained. I see her certificates and am happy.
I’m warned about the side-effects, which can include headaches and dizziness, and I’m told swelling and bruising after is normal.

After: I’m happy with the results and I can’t get over how easy it was

Droopy eyelids are also common in the first two weeks. I’m offered a two-week cooling off period so if I’m not sure, I can go away and think it over and return in 14 days if I’m still keen. She rubs an aesthetic cream into my crow’s feet and in between my eyebrows to numb the area ready for the needles — five in between the brows and three by each eye.

I lie down on the bed. The needles didn’t feel painful at all and it was over in less than half an hour.

Botox takes two weeks to have an effect. After, my skin looks a little red and I have a bruise on the forehead.

You can’t wear make-up for 12 hours post-treatment and you are advised against exercise for 24.

My nurse briefs me on what to do if I have concerns. It has all seemed very easy. It’s probably three days after the treatment when I start to notice a change. The creases are beginning to vanish, and even when I try quite hard to frown, the line has almost gone.

Superdrug is the first high street chain to offer £99 Botox injections in store
